I am getting an IP address conflict on a WinXP machine. My DHCP server is on Windows Server 2008 enterprise. I have checked the scope and that is not the issue. I have looked in DNS and WINS however nothing shows up out of the ordinary there either. I did an nbtstat -a with the address and it shows that machine only. I powered off that computer and did the nbtstat -a with the address again and nothing shows up. The machine will work for awhile and then it shows the bubble with an IP address conflict error. It then will not work with anything on the network. Does anyone have any ideas?
